Is there anything more terrifying in this world than a humanoid Gundam with more than 200 kilograms and a defense comparable to that of a main battle tank?

Of course, under the condition of appealing, the humanoid Gundam has a lot of combat experience and can quickly restore the armor.

When Lin An was cutting the spirit core, he specially instructed Senior Sister Dong beside him to help destroy the elemental crystals in it.

Make it completely turn into the kind of colorless and transparent spirit core orb that has no elemental preference.

Then Lin An placed these orbs in a certain order inside the limb joints that maintained the movement of the battle armor.

After painting the guiding spirit dust in a certain way, he put his mind at ease, let go of his trembling hands with excitement, and let out a long breath to prepare for the final lighting ceremony.

The girls around Lin An had already been a little dumbfounded by Lin An's operation.

It is not unheard of to use crystal nuclei to replace the soul joints of the machine and thus increase the elemental energy of the soul beast.

However, the spirit core is much more brittle than the soul steel after all.

Moreover, it is far more appropriate to form a set of such joint systems than to form a set of energy matrices.

Therefore, this set of technology is also regarded as a flashy theoretical fantasy, so it is abandoned and used.

Now I see that Lin An has taken out this set of technical means that have long been outdated.

The little hope that the girls had originally raised in their hearts for promotion also disappeared in an instant.

[Sure enough, it's just his crazy imagination, but it's a pity that he has been delayed here. 】

Dong Chan'er looked at Lin An's actions and didn't say a word, although she once had extremely high expectations for Lin An.

But now, the little hope in her heart was all extinguished, and she just sighed faintly and said no more.

Although he was still watching Lin An's non-stop work, he no longer had any hope.

As for Lin An, the moment he completed all the preparations, he naturally heard Senior Sister Dong's faint sigh.

When the voice reached his ears.

Lin An just tried his best to control his expression, so that he would not make a smug look on the corners of his mouth at this time as much as possible.

The Kedarin crystal technology of the Star Spirit has long exceeded the one-sided limitations of the world's understanding of the spirit core.

The practice of using psionic energy to form stable and strong crystalline parts can even be used as structural parts of the Arden's spear.

Of course, Lin An didn't put these spirit cores into them in order to treat them as important parts of moving joints.

Rather, it's embedded as part of the shield generator, and the mechanical parts that produce psionic crystals in battle when necessary.

Of course, these cores also contain a subsequent upgrade design for the Warguard Warframe.

But until then, the main thing is to exist in the Warframe as part of the refactoring protocol.

……

With all this preparation, it's time for the all-important upgrade to light up.

Lin An recalled Tanji, who was floating in the sky, and the girls left Lin An's position on the grounds of being vigilant.

This is the greatest tenderness that this group of kind-hearted beautiful girls can give Lin An.

His most important promotion moment was unexpectedly unwatched at the end.

Lin An has some regrets in it.

It's the flat-chested girl Whitina, I don't know if she's a cute girl with a big mind, or she's always maintained confidence in Lin An's upgrade plan.

At this time, she was the only one who was still looking forward to standing by Lin An's side, which was in stark contrast to the melancholy face of Senior Sister Dong Chan'er on the side.

Lin An didn't have much time to worry about these little things about vanity.

At this time, he had removed the detector armor of the little detective, revealing its original appearance.

Xiao Tanji, who reappeared in the form of a goldfish, first arched affectionately into Lin An's arms and arched again.

After Lin An stroked the metal shell of Xiao Tanji like a coquettish kitten.

This cute little machine reluctantly floated to the chest of the armor and fell into the pre-reserved socket from above.

It was the moment when Tanhime's metal parts intersected with her armor.

The unique spiritual energy belonging to the soul of the little detective Ji was transmitted to the whole body of the vigilant armor in an instant, stimulating the special resonance of the metal parts of the entire set of armor, causing it to emit a faint white light.

When Dong Chan'er saw this situation, she didn't have any happy thoughts in her heart.

Being able to activate the resonance of the battle armor can only mean that the research direction of this set of machine soul parts can be recognized by the machine soul.

Although this is a testament to Lin An's superhuman talent in mechanics from the side.

But for Dong Chan'er.

It is still far from the light that successfully activates the 60% resonance rate of the machine soul required to ignite.

In her eyes, the next thing that should have been for the white light to dissipate and the upgrade failed to happen.

But just a few seconds later, something beyond Dong Chan'er's experience and cognition happened.

I saw that the white light on the suit of armor did not dissipate, but became more and more dazzling.

Immediately after that, the surrounding elements began to stir, and frantically poured into Lin An's body of the promoted machine soul beast.

Then the white light flashed, and the white light gradually dissipated, and a unique yellow light began to emerge from the armor.

And the surrounding elements became more and more restless, and the speed of gathering was even beyond Dong Chan'er's cognition.

It's nothing to glow yellow at a promotion ceremony.

It just means that the synchronization rate of some parts is in the range of 30 points and 60 points.

It's a state that can be improvised, but it's not qualified.

If there is too much yellow light emitted from the promotion parts, it may even directly lead to the failure of the promotion ceremony.

However, in Dong Chan'er's eyes, the success of Lin An's suit of battle armor was enough to surprise her.

At this time, she was able to be promoted to the yellow level, which was really beyond her expectations.

But even so, she quickly realized that she had made a mistake in her judgment.

Because the speed of the surrounding elemental gathering is too turbulent, no matter how you look at it, it doesn't look like the synchronization rate of yellow light can cause an elemental commotion.

At this time, the girls who had been wandering around in order not to irritate Lin An also noticed the difference here.

With incredulous thoughts, they came back here to verify the facts.

However, he saw that the yellow light on Lin An's battle armor was displayed, and even the yellow light disappeared after a few seconds, and the entire set of battle armor emitted a unique blue light that would only have a pass rate of more than 60 percent.

"Jin ...... Successful promotion?! ”

"How is this possible?!"

"Didn't he design the promotion blueprint himself? The reasoning that comes from there can be a successful promotion in one go. ”

The three girls whose natal spirit beasts, including Lala Kuya, were machine soul octopuses, looked at the situation in front of them and talked nonsense.

As for Black Lily, she was stupid at the first sight of the blue light, and she couldn't say a word anymore.

But no matter how hard they believe it, the blue light on the mecha will not be faked, and since the fact is, even if it is impacting their experience, they can only accept it.

However, the outrageous thing has only just begun.

After Lin An's armor was successfully promoted, the blue light on it did not dissipate, but became more and more lush.

In a situation that the girls could no longer understand, the entire set of armor emitted a little orange light.

Immediately after that, even the orange light disappeared, and instead emitted a gentle green light, until finally all the parts of the entire warframe were frozen in the green light, greedily absorbing the surrounding elements.

"Blue is [Strong] Orange is [Lightweight] Gold is [Elemental Kick]

Green...... How can it be green? What does green stand for?!! ”

The light emitted by Lin An's soul when he was promoted had already exceeded the knowledge reserves of the girls.

At this time, Dong Chan'er, who is the daughter of the vice president of Wanling Academy, spoke with difficulty and said in an unbelievable tone.

"Green...... It means that the difference in the synchronization rate of the whole body parts will not exceed one percent, which means that the energy of the soul consuming the spirit core will be greatly reduced. ”

As Dong Chan'er's words fell, they reached the ears of everyone.

Lin An's machine soul promotion was also completely completed.

The green glow of the Warguard armor had faded, revealing the pale gold of the armor itself.

Lin Anxin, who had been successfully promoted to a first-order summoner, looked at the little detective in front of him with satisfaction, wearing the vigilant battle armor.

He keeps moving his limbs and making a variety of movements.

It took a while to notice the group of girls standing behind him, who were already stunned.
